Title (EN) POWER CONVERSION SYSTEM
(FR) SYSTÈME CONVERTISSEUR DE PUISSANCE
(JA) 電力変換システム
Abstract:
(EN) The purpose of the present invention is to reduce surge associated with changing of switching states without increasing the torque ripple of a motor. A first switching signal (Sbp) for controlling the switching of a boost converter is generated based on the comparison between a first duty command value (Db*) of the boost converter and a first triangular wave carrier (carrier1). A second switching signal (Sup1) for controlling the switching of an inverter is generated based on the comparison between a second duty command value (Du1*) of the inverter and a second triangular wave carrier (carrier2). The second triangular wave carrier (carrier2) is generated so that the frequency thereof becomes equal to that of the first triangular wave carrier and the phase thereof becomes different from that of the first triangular wave carrier by 180 degrees.
(FR) La présente invention concerne la réduction des crêtes associées au changement des états de commutation sans augmentation de l'ondulation de couple d'un moteur. Un premier signal de commutation (Sbp) destiné à commander la commutation d'un convertisseur élévateur est généré en se basant sur la comparaison entre une première valeur d'instruction de service (Db*) du convertisseur élévateur et une première porteuse d'onde triangulaire (carrier1). Un second signal de commutation (Sup1) destiné à commander la commutation d'un onduleur est généré en se basant sur la comparaison entre une seconde valeur d'instruction de service (Du1*) de l'onduleur et une seconde porteuse d'onde triangulaire (carrier2). La seconde porteuse d'onde triangulaire (carrier2) est générée de telle sorte que sa fréquence devienne égale à celle de la première porteuse d'onde triangulaire et que sa phase devienne différente de celle de la première porteuse d'onde triangulaire de 180 degrés.
(JA)  モータのトルクリプルを増大させることなく、スイッチング状態の切り替えに伴うサージを低減する。 昇圧コンバータのスイッチングを制御する第1スイッチング信号(Sbp)は、昇圧コンバータの第1デューティ指令値(Db*)と第1三角波キャリア(carrier1)との比較に基づいて生成される。インバータのスイッチングを制御する第2スイッチング信号(Sup1)は、インバータの第2デューティ指令値(Du1*)と第2三角波キャリア(carrier2)との比較に基づいて生成される。そして、第2三角波キャリア(carrier2)は、当該第2三角波キャリアの周波数が前記第1三角波キャリアの周波数と同じになるように、かつ当該第2三角波キャリアの位相が前記第1三角波キャリアの位相と180度異なるように、生成される。
